STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 287,094, dated October23, 1883.`

' Application filed August 4,1883. (No model.)

To all whom it 17mg/ concern.-

Be it known that I, WILLIAM W. CAMPBELL, of the city of' San Francisco,county of San Francisco, and State of California, have invented anImprovement in Street or Station Indicators, and I hereby declare thefollowing to be a full, clear, and exact description thereof.. l

My invention relates to certain improvements in devices by which streetsor stations are indicated, when reached, to passengers withinrailway-cars; and it consists of' a band .or belt passing around certainsupportingrollers, and a mechanism by which they are caused torotatefsaid mechanism being connected with a device beneath the carhaving an arm to enter the grip-slot of a cable-tube, and be actuated bymeans of' lugs or projections fixed at the proper positions within thetube, as will be more fully explained by reference to the A accompanyingdrawings, in which- Figure l is a longitudinal section of' a car,showing my apparatus and its connection. Fig. 2 is a transverse section.Figs. 3 and 4 are views of the device for operating the mechanism androlls. Fig. 5 is a vertical section ofthe case and rollers and band.Figs. 6, 7, and 8 are views of the operating mechanism.

A is a car having supporting-wheels B, run- In the present case I haveshown my invention adapted to be used upon streetrailways in which thecars are propelled by means of a cable traversing an underground 'tubeor tunnel, and a suitable griping mechanism by which the car may beconnected with the rope.

D is the cable tunnel or tube, and it has lugs or projections E fixed atone side within it, out of the way of the grip-shank.

Upon the bottom of the car is fixed a'device by which the cords Fare-operated, and an arm, G, projects downward from it into the tube,and is bentl at right angles, as shown at H, so that as it arrives atone of the lugs E it will be turned about its axis. The shaft G, towhich the arm His fixed, extends up vertically through a guide, I, andhas arms J extending horizontally at its top, and crosswise of the car.To the ends of these arms the cords or wires F are iixed, and extendforward to the end of the car and around pulleys L, so

another slide, P, moving in the same case or 6o guide with the slide M,and having the other part of the cord xed to its opposite end. When thecord attached to the first slide, M, is pulled by the action of the armJ, the lug N engages the button O, and thus draws the slide 'P and itscord until the lower or back end of the button strikes a lug, Q, uponthe inside ,of the case, which .throws it forward and thus releases itfrom the catch N, and allows it to be returned by a suitable springattachment which is connected with the mechanism hereinafter described.The hook N has its lower pivoted end formed with a bell-crank lever, asat N', to which the cord or wire is attached, and a spring holds thehook out of contact with the part O until the cord is pulled, when thefirst motion throws the hook forward so as to engage the catch O, and afurther pull draws the slide M down. By thisl arrangement that part ofthe cord which 8o is connected with the band-moving mechanism is alwaysreleased at the same point, and

the band will not be moved beyond the point necessary to exhibit thestation desired; but

the arm J and its connected slide M may be moved farther, if thecar-should be running fast and the arm G should strike the lug withinthe tube violently. This device may be placed'at any suitable pointbetween the operating-levers and the band or belt meehan- 9o ism, butpreferably near the latter, so that when the hook N of one side isdetached and the other operated, there will be but a short length of theidle cord to be moved. The cords or wires from the arms J, after passingaround the pulleys L,lead up to a point preferably in the upper frontend of the car, and connect with slides M, as above described. Then thewires or cords from slides P pass partly around upon opposite sides of`a rim, R, which is grooved to receive them, and are attached, one totheend of each of the levers S, which cross diagonally within the rim, andhave their inner ends pivoted at T, as shown.

IOOr

.cord back toits place.

rllhe outer ends pass through slots in the rim and project a shortdistance, so that the cords may be attached to them, as shown. The rim Rfits within an outer rim, U, the interior face of'which is toothed orcorrugated, as shown. The operation will be as follows: The levers Shave their inner ends pivoted below the center of the rim R and the lineof attachment of the cords F, and when the cord upon either side ispulled it will pull the end of the lever S, to which it is attached,outward until it engages with the teeth or corrugations in the rim U, sothat its further movement causes the rim U to be revolved also. As soonas the leveris released by the action of the slides M and P and thebutton O, the spring V draws the lever and The rimR is returned to itsposition by means of a spring, V.

lV is a belt, band, or ribbon of any suitable material,having the namesof the streets or stations printed upon itat equal intervals, and as thebelt is moved by the action of the cords and levers it will be advancedso as to carry the Y names forward a certain fixed distance at each 1movement. The belt is passed around a nu mber of rolls or carriers, X X,within an inelosingcase, Y, so as to provide as great alength as isnecessary to carry all the names, and three of these rolls are driven bya gear-wheel, Z, i

upon the rim U, so as to prevent the possibility ofthe slipping of thebelt. The arrangement `of gears for the purpose is well shown in Fig.

be fixed so as to be automatically sounded' when anew station is broughtforward and exposed to view. rllie station or street names are soarranged that when moved forward each one will be left in the opening`or slot so as to be easily seen.

It will be manifest that there will be a set of slides, M l?, with thebutton O, and catch N, for each ofthe cords F,-so that the belt may bemoved either forward or backward at will; and it will also be seen thatthe mechanism R S U might be omitted and the work done by the slides M Pwith the catches O and bell-crank hook-levers N N if desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a cable-railway, a means for indicating streets or stations,consisting of an endless name band or belt passing around rollers withina case in the car, and cords or wires connected with these rollers andleading toayoke beneath the ear, in combination with a vertical stem towhich the yoke is fixed, said stem extending down through the grip-slotof the cable-tunnel, and having an arm or arms l which will be engagedby fixed lugs or projections within the tunnel, so as to partiallyrotate the shaft and move the belt, substantially as herein described.

2. A mechanism for moving an endless station-indicating band or belt,consisting of a vertical rotating shaft passing through the slot of acable-railway tube or tunnel, and having an arm to be turned byprojections xed within the tube, in combination with a cross-arm fixedto the upper end of the shaft, and cords or wires leading from its endsto levers by which the mechanism is actuated, substantially as hereindescribed.

3. In a street or station indicator, a means for limiting the movementof the cords or wires connected with the belt-carrying mechanism,consisting of the slides M and P, to which the two parts of a cord areattached, the lug N, swinging button or catch O, and the lug Q,substantially as herein described.

4. In a street or station indicator, the rim R, having the levers S,pivoted on the inner opL posite sides'crossing cach other and extendingthrough slots in the periphery of the rim, in combination with theexterior rim, U; toothed or corrugated, as shown,beltcarrying mechanism,and the cords or wires connected with the levers, substantially asdescribed;

5. In a street or station indicator, the rolls or carriers X, aboutwhich the bandWpasses, in combination with the rim R, havingoperating-levers S, the exterior toothed or corrugated rim, U, and anintermediate gearing by which two or more of the carriers are drivendirectly from the geared rim U, substantially as and for the pui-poseherein shown and described. f

6. In a station-indicator having an endless band carrying the naines anda mechanism for moving the same, the slide l), having one end of thecord attached to it, and the trip lever or button O, in combination withthe slide M, having the bell-crank hook-lever NV N, to

which the other part of the cord may be attached, substantially asherein described.

In witness whereof I have hereunto set my hand. u
